Abstract: THE PRESENT INVENTION RELATES TO A PROCESS FOR THE PRODUCTION OF AN IMPROVED POLYORGANOSILOXANE COMPOSITION CONVERTIBLE BY HEATING TO THE SOLID ELASTIC STATE WHEREIN CERIUM CARBONATE IS MIXED WITH THE POLYORGANO-SILOXANE IN ORDER TO REDUCE THE CURING TIME THEREOF AND IN ORDER TO INCREASE THE THERMAL STABILITY OF THE CURED ELASTOMER.

Abstract: COMPOSITIONS COMPRISING LINEAR ORGANOPOLYSILOXANES, WHICH ARE TO BE CONVERTED INTO A SOLID ELASTIC STATE BY ADDING AN ORGANIC PEROXIDE AND SUBSEQUENT MOULDING AND HEATING, CAN BE IMPROVED ACCORDING TO THE INVENTION BY A TREATMENT WHICH COMPRISES THE ADDITION OF CERTAIN COMPOUNDS RELEASING NITROGEN AT ELEVATED TEMPERATURE, AND HEATING THE RESULTANT MIXTURE AT THE SAME TIME OR LATER UNTIL THESE NITROGEN COMPOUNDS HAVE BEEN DECOMPOSED. SUCH TREATMENT ENABLES THE COMPOSITION TO BE CONVERTED WITHOUT THE EXTENSIVE FINAL HEAT-TREATMENT OF THE MOULDED ARTICLES, WHICH IS NECESSARY IN THE PROCEDURE HITHERTO KNOWN IN THE ART.
